    My Polaris Trail Boss 350 won't run.
    I'm working on a Polaris Trail Boss 350. With a 2 stroke engine. At one point I had it running, and now it won't start. It has good compression and spark. I have taken the carb off and cleaned it thoroughly, and I have changed the spark plug. It acts like it's not getting any fuel to the combustion chamber Even tried removing the carb and spraying a bit of gas into the intake still didn't get any results, and finding a service manual for this ATV is proving to be difficult as well. Any help would be greatly appreciated.

    Have you taken the spark plug out and given it a shot of gas or starter fluid? I know it is not a good idea to use starter fluid but just a little shot should not hurt it. If it fires, that should prove you have a fuel problem.
